Software Protect Key

[zalmey]

Hi All
Dears i want to protect my software using the dll file. How can i protect. I am a new bie. guide.

the simplest way would be to use the reg, have a standard key and test to see if it is in the reg

look at GetSetting SaveSetting

The key could be as simple as all numbers in a block have to add upto a number using the ascii key value of the char for the alphas

VB has some built in protection that you can use for ActiveX controls. Look in the index of the VB docs under "license".

I'm not sure if this is what you are looking for, but it might help get you started:

Licensing Issues for Controls

Licensing for controls is a sensitive issue. After you've spent hundreds of hours developing a control, what if somebody else puts an instance of it on a UserControl, exposes all the properties, methods, and events, adds one or two trivial properties, then compiles and sells it as a new control?

Visual Basic's licensing support protects your investment. When you add licensing support to your control component, a license key is compiled into it. This key covers all the controls in the component.

Running your Setup program transfers the license key to another computer's registry, allowing your controls to be used for development. Simply copying your .ocx file to another computer and registering it does not transfer the license key, so the controls cannot be used.

To add licensing support to your control project

On the Project menu, click <MyProject> Properties to open the Project Properties dialog box. Select the General tab, check Require License Key, then click OK.
When you make the .ocx file, Visual Basic will create a .vbl file containing the registry key for licensing your control component. When you use the Package and Deployment wizard to create a setup for your .ocx, the .vbl file is automatically included in the setup procedure.
